Fess edges SearXNG 92 to 73, and most of the difference is release recency: fess-15.9.0 from 15 days ago against no tagged release. SearXNG has the largest following at 39k stars, yet ranks #2 of 3, held back mostly by release recency (no tagged release).
The most recent release is Fess fess-15.9.0, published 15 days ago. SearXNG and Yacy publish no tagged releases, which costs up to 25 of the 100 points. None of the measured options scores under 40. By stack, Java (2) and Python (1) are the most common. Fess is permissively licensed; SearXNG and Yacy are copyleft.

1 of 3 are permissively licensed (MIT, Apache, BSD or similar): Fess (Apache-2.0). 2 use copyleft licences such as GPL or AGPL, which require you to publish changes if you distribute a modified version.
3 of 3 publish a Docker image or Compose file: Fess, SearXNG, Yacy. Docker support contributes 10 of the 100 available health points, because it is the clearest signal that self-hosting is a supported path rather than an afterthought.
